The CD player works as advertised. The single ended headphone jack has decent output, able to drive IEMs at a loud volume level. The coaxial output also works with a 3.5mm male to coaxial cable hooked to a pre-amp. Sound signature is unolocured in the territory of neutral to slightly bright neutral and corresponds well with recording and mastering of records. Worth the money imo.

If my current HiBy R6 III (Gen 3, ESS) is compared to driving a BMW, the R6Pro MAX is a Rolls Royce.

It is easy, smooth, and suave. It doesn’t make a big deal of representing a soundstage that’s exactly studio-like. Natural, not heavy on any particular frequency (do not expect heart thumping bass) and extremely coherent. It’s like you’re sitting in front of the artists themselves, in a studio, with a performance made just for you alone. Each frequency - the lows, mids, highs and everything else in between - are effortlessly detailed and precise.

All IEMs I have tried with it, i.e. the 64 Audio Volür, Symphonium Meteor, Penon Quattro and Kiwi Ears Quintet are driven best at Low or Middle Gain, with me personally finding that High Gain makes it all muddy. I am yet to try it with my HiFiMan Ananda Planar headphones, and will update this review as the journey with this masterpiece of a device continues. Rarely do I find myself being fondly attached to any device so quickly. It may be safe to say the R6Pro MAX does have something special. Only time will tell.

Lastly, the design is phenomenal and classy. The weight of the unit is evenly balanced and not top-heavy, making it very easy to handle in spite of its 500 gramme weight.

My only gripe, because I just HAVE to find one is that the case provided is quite impractical as the device tends to slide out from the top opening, and it interferes with the UI gestures. On the flip side, the quality of the case is top-notch making the device feel extremely premium with its carbon fiber-like finish.

Kudos to HiBy. Clearly a lot of effort and thought has been put into introducing something like this. We may be looking at a potential market game-changer.

Superb Audio quality, Enhance the sound separation for my moondrop chu 2. i enjoyed a lot. Built quality also so good. Best Budget DAC recommended.

Bought the KZ Castor Pro from Audiostore, and I must say, I am extremely happy with my purchase. At first, I was a bit hesitant to order from them, but they completely surprised me with their service.

The delivery was super fast—much quicker than I expected! I couldn't believe how quickly the IEMs reached me, which made the entire shopping experience even more satisfying.

The product AUDIOCULAR D07 is a phenomenal DAC & Amp. It is suitable for all kinds of wired earphones. The output impedance of this DAC is sufficient for inexpensive as well as Expensive earphones. Overall I satisfied very much with this product. Thank you.

I really liked Moondrop Chu II DSP, which was my first IEM. I felt like I needed some more bass. This is perfect. Sounds exactly same as Chu II and with more bass. Shipping and delivery was also very fast. Got it delivered in 3 days. Good delivery and good product.

Sharp & Crystal clear audio🤩

For the price you can't get better value when comparing with TOTL iem's from other manufacturers, regardless of driver technology and implementation. The bone conduction driver works, which is always a plus.

Enough BASS, Treble not harsh. Smooth cable. Also, actually I've Tangzu Warner in my opinion, but i selected this. Satisfied with this IEM. Delivery was fast! Thank you TAS!!!!!

I was searching for mid forward, vocal centric IEM. Looking at options like oracle, mega5est etc. Mr. Pritam was kind enough to attend my numerous calls and indepth discussion and finally suggested me to penon voltage. Hefty price tag and becuz of my already good collection, I was not tempted for any iem if not drastically different sound signature. Again my man Friday Pritamji allowed me audition of his personal set of penon voltage.
Penon voltage is honestly outstanding and justify every penny.
Midst are lush and superb. Treble is outstanding. Male and female vocals are life like. Technically top notch. Base is full and extends deep and thumping. Best part is timber. Jazz, vocals and classical sounds so natural, it seems intimate and soulful. I had u12t, campfire Solaris og, now I have a 64audio volur, but voltage has etched a unique image in my soul. It's sounds like a headphone rather than an iem. Penon audio has an ace up their sleeves.

D32 is way better than expected. Sound imaging & separation is very good. Nice thumpy bass, crystal clear mids. Overall very value for money stuff. All bluetooth codec available. Supports aux in from DAP for hires audio. Fantastic overall.

For quite a long duration, I was looking for an budget IEM with a size that would perfectly sink within ear lobe and will not exert any pressure while being a couch potato , on one side. Atlast this is where the search ended.
Aurora is even a bit smaller in size than Sennheiser IE100 Pros, which were my only go to solution at late nights. I already referred to various other reviews about the sound signature of this tiny one, and was quite confident about the other end of the bargain any way. I will not be hence touch the audio signature stuff , since there are plenty detailed reviews on the youtube and many other forums already. It is the ergonomics which is mostly untouched area of any in ear type monitors, that was more profound for me in this case, for long duration of usage. Also liked the quality of the case supplied with , the whole package is absolutely incredible !

This iem fits like a glove, it is so well tuned. The sound profile changes based on what you plug it into.
I was searching for an IEM that fits comfortably for soo long and then I came acrosss this review by Acros. I immediately jumped on it as soon as he said it was light, because so many reviewers talk about how an IEM looks and sound signature and more but never about its weight and fit. He did a comparison with few similarly priced IEMS. This one when compared to Moondrop Aria which I have sounds awesome but it is a pain when wearing it for more that 30 mins. This one I have worn for 3 hours straight and nothing. Perfect for my needs.
I drive it with Fiio BTR3K specifically for the sound profile it offers, on the other ones it sounds too neutral. Thank you Audio Store for stocking this IEM.

Excellent delivery experience, it was a gift wrap.
My first time ordering from the audio store, really impressed.
And the device is marvelous.

Comfortable & Excellent quality. As per heard, i was looking adaptor for my Tangzu Warner sg wired IEM. This KZ AE01 fulfilled my needs for bluetooth adaptor. Music sound quality is good. Fitting is also fine. Call quality is little bit low.
Otherwise ok for bluetooth conversion of IEM.
